Synthesis, Characterization and Corrosion Protection Properties of Imidazole Derivatives on Mild Steel in 1.0 M HCl

1-(2-Dodecylsulfanyl-ethyl)-1H-imidazole (DSEIm) and 2-Imidazol-1-yl-ethylsulfanyl)-acetic acid (ImESAA) were synthesized via radical catalysis method and characterized using H-1 NMR and C-13 NMR spectroscopy. The corrosion performances of mild steel specimens were studied by three imidazole derivatives include: 1-vinylvinylimidazole (VyIm), DSEIm and ImESAA, which were investigated in 1.0 M HCl using weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopic (EIS) method. The results obtained show that DSEIm is the best corrosion inhibitor; its inhibition efficiency (E %) increases with increasing the inhibitor concentration, but decreases with the raise of temperature. Potentiodynamic polarization studies clearly revealed that the inhibitors changed the mechanism of hydrogen evolution, and that they acted as mixed inhibitors, but most effectively in the cathodic range. The higher values of activation energy (Ea) in the inhibited solution can be correlated with the increased thickness of the double layer; this is interpreted with physical adsorption of the inhibitor onto the metal surface resulting in the formation of a surface film. Adsorption of imidazole derivatives have been studied with Monte Carlo simulations.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 288-32-4. Recommanded Product: 1H-Imidazole.

Low-toxicity copper corrosion inhibitors

The efficiency of various imidazole derivatives as corrosion inhibitors for copper in hydrochloric and sulfuric acids (HCl and H2SO4) was investigated. Electrochemical measurements showed the organic compounds investigated have fairly good inhibiting properties, except for 4-methyl-5-imidazole-carbaldehyde in HCl. Protecting properties of most imidazole derivatives were close to those of commercial inhibitors for copper. Evaluation of the toxicity of the water solutions on the biological system for treatment of waste water – as measured in regard to chemical oxygen demands (COD), aerobic, and anaerobic toxicity – showed the tested inhibitors have relatively low toxicity.

Phosphine-free palladium-catalysed direct 5-arylation of imidazole derivatives at low catalyst loading

The regioselective 5-arylation of imidazole derivatives with aryl bromides using a low loading of a phosphine-free palladium catalyst gives a simple and economic access to the corresponding 5-arylimidazoles. The choice of the base and of the solvent was found to be crucial to form these products in high yields. Using KOAc as the base, DMAc as the solvent and only 0.5-0.01 mol % Pd(OAc)(2) as the catalyst, the target products were obtained in moderate to good yields with a wide variety of aryl bromides. Substituents Such as fluoro, trifluoromethyl, formyl, acetyl, propionyl, ester OF nitrile on the aryl bromide are tolerated. Sterically congested aryl bromides or heteroaryl bromides can also be employed. The nature of the substituents on the imidazole derivative has an important influence on the yields.

Isoprene-Mediated Lithiation of 1-Alkylimidazoles: Chiral Induction of the Alkyl Substituent

The isoprene-mediated lithiation of imidazoles bearing a secondary alkyl substituent at the nitrogen (7, 8 and 13) and the subsequent nucleophilic addition to different electrophiles allows the preparation of the corresponding 2-functionalized imidazoles 10, 11 and 14. The presence of a stereogenic center in the alkyl substituent induces diastereoselection during the nucleophilic addition step with a prochiral electrophile (i.e. pivalaldehyde), producing the expected imidazole derivative with excellent overall yield, but low de (up to 26%).

Screening novel, potent multidrug-resistant modulators from imidazole derivatives

The overexpression of P-glycoprotein (P-gp) by tumor cells results in multidrug resistance (MDR) to structurally unrelated anticancer drugs. Combined therapy with MDR-related cytotoxins and MDR modulators is a promising strategy to overcome clinical MDR. This study was designed to screen potent MDR modulators from imidazole derivatives. Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The intracellular accumulation of doxorubicin (Dox) was detected by fluorescence spectrophotometry. The function of P-gp was examined by Rhodamine 123 accumulation detected with flow cytometry (FCM). Among imidazole derivatives, FG020326, FG020327, and FG020318 were found to possess three- to fourfold stronger reversal MDR activity than verapamil, a well-known positive MDR modulator. Imidazole derivatives significantly increased the Dox accumulation and inhibited P-gp function exhibited by the increase of Rhodamine accumulation in MDR cells. The fold reversal of MDR was relative with the increase of Rhodamine accumulation. FG020326, FG020327, and FG020318 showed potent MDR reversal activity in vitro. Their mechanism of MDR reversal is associated with the inhibition of P-gp function and the increase of anticancer accumulation. These results suggest FG020326, FG020327, and FG020318 are promising to further study and develop.

Iron-Phosphonate Nanomaterial: As a Novel and Efficient Organic-Inorganic Hybrid Catalyst for Solvent-Free Synthesis of Tri-Substituted Imidazole Derivatives

In this study, organic-metal nanocatalyst was synthesized by reacting ferric(Iota Iota) chloride with organic phosphonate ligand. The particle size was controlled with the help of the surfactant. Nanoparticle structure was analyzed using Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), scanning electron microscopy (SEM), dispersive X-ray (EDX), Brunauer-Emmett-Teller (BET) isotherm and X-ray diffraction (XRD) spectra. Next, its catalytic activity was investigated in the synthesis of heterocyclic compounds (2,4,5-trisubstituted imidazoles derivatives). Under optimal conditions, the products were obtained with good efficiency and short time. Products identification were evaluated using physical data, FT-IR, H-1 and (CNMR)-C-13 analysis.
